Water Safety Plan – Book 3: Capital Management Version 1: Issue 3 – Date July 2019 Page 6 of 18

In order to ensure that all designs are developed in accordance with the requirements detailed above, all designs, before offered for Tender, the Projects Team and Independent Consultants shall review each design for compliance, suitability and correctness of specification.

The Projects Team and Independent Consultants shall verify and ratify each design and confirm that it is suitable for tendering purposes and issue a suitably completed 'Certificate of Design Compliance' shall be issued when each submitted design has been found to be compliant with all requirements stipulated above.

1.4 Installation Verification:

The system shall be regularly checked during installation to ensure that it is being carried in accordance with the requirements detailed above and as specified in the relevant scheme design specifications and contractual agreements.

In the absence of a scheme Clerk-of Works, the FM Responsible Person/Team Leaders should verify and ratify each installation (or stage thereof) and confirm that it is found to be compliant with all requirements stipulated above and issue a suitably completed 'Certificate of Installation Compliance' shall be issued when each completed installation has been found to be compliant with all requirements stipulated above.

1.5 Commissioning:

Correct commissioning is vitally important for the satisfactory operation of the hot and cold water systems. The designer should prepare a commissioning brief for use by the contractor’s commissioning engineer. This brief should specify fully and clearly the extent of the commissioning and the objectives which must be achieved, and should include:

i. full design data on temperatures, chemical levels, water flow rates and pressures; ii. plant and equipment data; iii. number commissioning procedures for thermostatic mixing valves in accordance with

specification; iv. drawings and schematics; v. microbiological activity levels; vi. a list of test certificates to be provided; vii. water quality (Legionella) risk Assessment.

The designer shall prepare for inclusion in the contract documents a list of tests and measurements that are to be taken by the contractor and recorded by him/her. These shall be witnessed by the contract supervising officer or project engineer on his/her behalf and he/she, if approved, will circulate the results, in accordance with the client’s instructions. The installation, on completion, shall be operated by the contractor as a whole, and subjected to functional or performance tests as specified by the designer.

The commissioning manual shall be prepared by the contractor and submitted to the client’s commissioning adviser for review before being issued in final form. Typical schedules of

Water Safety Plan – Book 3: Capital Management Version 1: Issue 3 – Date July 2019 Page 7 of 18

checks and performance tests shall be included in the commissioning manual together with record sheets. These shall be amended and supplemented as the designer considers necessary. Once the client’s commissioning adviser is satisfied that the system meets the design intent, the final accordance record sheets should be completed. If performance is not acceptable, the matter should be dealt with in accordance with the contract requirements.

The supervising officer or project engineer, who shall countersign any relevant test record documents, shall witness commissioning and testing. “As installed” record drawings, schematic diagrams, operating and maintenance instructions must be supplied at the time of handover. Certified records of pressure testing and disinfection shall also be made available. The whole commissioning procedure shall be carried out under the guidance of a single authority, although the involvement of specialists or manufacturers may be required for specific items of plant. Valid calibration certificates shall be submitted and checked for all measuring equipment to be used by the commissioning engineers prior to commencement of commissioning. The commissioning should be carried out in a logical and methodical manner.

The installation, on completion, shall be operated by the contractor as a whole, and subjected to specified functional or performance tests. Once the system meets the design intent, the final completion record sheet(s) shall be completed. In the event of performance not being acceptable, the matter should be dealt with in accordance with the contract requirements.

It is essential that a full report of all commissioning and testing activities is compiled and handed over to be incorporated within the operation and maintenance manuals. These commissioning and testing records will be required so that subsequent maintenance and periodic checks can be made to ensure that the installation continues to operate as intended.

In the absence of a scheme Clark-of Works, the Projects Team and Independent Consultants shall verify and ratify each installation (or stage thereof) and confirm that it is found to be compliant with all requirements stipulated above and issue a suitably completed 'Certificate of Installation Compliance' shall be issued when each completed installation has been found to be compliant with all requirements stipulated above.

1.6 Hand-Over:

Following any alteration to the Water system the installation will be accepted back by FM by the nominated representative of the appropriate FM department. This person will be trained and competent in Water Management and appointed by the University to carry out such tasks.

Hand-over of all new-builds and refurbishments must not be carried out until all of the requirements detailed in the relevant processes described below are satisfied and the appropriate process and permit (Permit No. 5 'Permit for Hand-over and Occupation of new- builds' and Permit No. 6 'Permit for Hand-over and Occupation of Refurbished Facilities') are completed and duly signed:

Water Safety Plan – Book 3: Capital Management Version 1: Issue 3 – Date July 2019 Page 8 of 18

A. System Flushing

Once filled, systems should not be drained unless full disinfection is to be carried out prior to building occupancy and use. However, allowing water in newly installed plumbing to stagnate can result in water borne bacteria (biofilm) growing and proliferating in the storage vessels and peripheral parts of the domestic water system. To reduce the risk of this, it is recommended that flushing should take place on a on a Weekly basis (2xWeekly or more frequently if deemed necessary) to introduce fresh water throughout the system.

To prevent the accumulation of biofilm during construction and testing, continuous dosing of water systems with appropriate biocides should be considered. Such treated systems should be regularly flushed to ensure that the biocide reaches all parts of the systems, and particularly outlets.

Dosing with an appropriate level of biocide as soon as water hits a pipe or storage vessel, along with regular flushing, can control the accumulation of biofilm more effectively. Once started, this procedure has to be sustained and logged, as lapses can result in a critical increase in water borne bacteria at the outlet.

B. System disinfection:

The required water quality shall be achieved by the use of shot-dosing of a suitable disinfecting agent, the levels of which must be maintained within the recommended limits for achieving disinfection as specified within the current edition of BS8558:2015: Clause 5.2.3 Flushing and Disinfection and L8 – The Control of Legionella bacteria in water systems – Approved Code of Practice & Guidance 2013.

Proprietary solutions of disinfectant should be used in accordance with the manufacturers’ instructions. The COSHH Regulations require that the risks from using the disinfectant for each task be assessed to ensure that the control procedures adopted are suitable for the particular application.

Incoming Mains (MCWS) Distribution System and all outlets

Confirmation that the incoming mains supply was flushed at least 2 x weekly prior to connection to system Confirmation that, once wetted for pressure testing, all parts of the system have been subject to a Weekly (2xWeekly or more frequently if deemed necessary) flushing programme or that the level of biocide dosed was within recommended levels during this period (ClO2 @ minimum of 1ppm (mg/L). Alternatively, where pressure testing was carried out 'dry', this needs to adequately certificated by the project supervisor Confirmation required that the flushing included locations which may be capped-off whilst awaiting future connection to equipment and/or other facilities and that any machines (such as washing machines etc.) already connected to the system are removed during the disinfection process to allow for disinfectant solution to be drawn and made available to these areas. Confirmation that the system has been subject to at least 2 x weekly flushing following disinfection.

Water Safety Plan – Book 3: Capital Management Version 1: Issue 3 – Date July 2019 Page 9 of 18

Disinfection should not be undertaken before materials, for example linings in cisterns, have fully cured. Advice should be sought from equipment manufacturers to ensure that proposed disinfection chemicals will not adversely affect performance. No heat source should be applied during the disinfection procedure, including final flushing. The disinfection must be carried out as close to hand-over (and occupation) as practicable.

C. Temperature/ClO2/Cl Profiles

These tests shall be performed prior to contractual handover and bringing the system into use. Separate thermostatic measuring and recording equipment should be used, that is, independent of any building management system. It will be necessary to have systems fully operational and to simulate typical draw-off of water. Once disinfection has taken place, it is essential to put in place measures to ensure that hot and cold water temperatures are maintained. This will require regular flushing, at least weekly, and possibly more frequently during periods of hot weather.

Water temperatures and ClO2/CL levels to be recorded three times equally spaced over 24 hours, under simulated maximum usage requirements, to demonstrate that the recommended temperatures are being achieved. Temperature and ClO2/Cl measurement equipment and water sampling equipment shall be suitably calibrated via UKAS calibration and accredited to ISO 17025 and calibration certificate made available.

Incoming Mains (MCWS) Confirmation that the incoming mains supply has been suitably disinfected prior to connection to system.

Water Storage Tanks/Hot water Confirmation that all storage tanks and hot water generation Generation Vessels vessels/equipment have been suitably disinfected Outlet Fittings Confirmation that all taps, shower heads, TMVs, associated strainers and

aerators have been dip-disinfected prior to final connection. Distribution System and all outlets Confirmation that disinfection was carried out in accordance with the

relevant specifications listed above and that it included all parts and outlets of the system. Confirmation required that the disinfection included locations which may be capped-off whilst awaiting future connection to equipment and/or other facilities and that any machines (such as washing machines etc.) already connected to the system are removed during the disinfection process to allow for disinfectant solution to be drawn and made available to these areas. Confirmation that suitable water samples have been collected and submitted for microbiological analysis not earlier than 48hrs following disinfection.

Guidance Note 1: Chlorine dioxide will normally be used as the hyper-chlorination disinfectant agent throughout. This process must only be carried out by suitably equipped and trained personnel form approved contractors who are members of the Legionella Control Association or by suitably equipped and trained University personnel.Where alternative disinfection agents are intended for use, a written proposal outlining the reasons why analternative disinfection agent is proposed for use, the proposed disinfection agent, COSHH sheets, risk assessment and methodology shall be presented to the FM Department Responsible Person for written authorisation.Alternative disinfection agents shall not be used without prior written consent from the Responsible Person (FM).Although chlorine dioxide is known to be more effective in the destruction of biofilm in domestic water systems,sodium hypochlorite is easier and safer to handle at high concentrations (used for hyper-chlorination).

Incoming MCWS After 2 minutes of running cold water the temperature to be reached

shall be maximum 20oC

Cold Water Storage Measure and record the Incoming MCWS. Temperature not to exceed 20oC. Measure and record the stored water. Temperature not to exceed 20oC.

Hot Water Generation and Storage

Measure and record the Set temperature setting of the thermostat (if fitted and calibrated). Temperature to exceed 60oC. Measure and record the “Flow” temperature using a contact thermometer or fitted gauge. Temperature to be taken from Flow pipework as close to the Calorifier as possible. Temperature to exceed 60oC Measure and record the Return temperature using a contact thermometer or fitted gauge. Temperature to be taken from Return pipework as close to the Calorifier as possible. Temperature to exceed 55oC in clinical areas and 50°C in all “other” areas. Isolate Cold Feed and open drain point and measure and record temperature. Temperature to exceed 60oC within 1 minute. Measure and record the Cold Feed temperature using a contact thermometer or fitted gauge. Temperature to be taken from cold feed pipework within one metre from the Calorifier. Temperature NOT to exceed 20oC. Where the unit is monitored using BMS, collect the readings of all the fields listed above, for at least a 24hr period and consider the results. Adjust control parameters as necessary.

HWS After 1 minute of running hot water the temperature to be reached shall be minimum 55oC in clinical areas and 50°C in all “other” areas.

MCWS/CWS After 2 minutes of running cold water the temperature to be reached shall be maximum 20oC Maximum 2oC higher than that at the point of supply.

Blended HWS to the TMV minimum 55oC in clinical areas and 50°C in all “other” areas. CWS to TMV maximum 20oC 41oC (+ 1oC) for showers 41oC (+ 1oC) for basins 44oC(+ 1oC) for baths 38oC (+ 1oC) for bidets

ClO2 Point of injection – between 0.25 and 0.8ppm (Note: 0.8ppm must be consider as the maximum allowed level at point of injection and it is only allowed at this level at this point in order to allow for the minimum levels to be achieved at the point of delivery). Any level fluctuations must only be tolerated within this range and care must be exercised to ensure that the level of ClO2 at the nearest outlet does not exceed 0.5ppm. Point of delivery (measured at sentinel outlets) – between 0.25 and 0.5ppm

Chlorine (Microchem M101) Point of injection – between 0.6 and 1ppm at dissolver tank. Any level fluctuations must only be tolerated within this range and care must be exercised to ensure that the level of Cl2 at the nearest outlet does not exceed 1ppm. Point of delivery (measured at sentinel outlets) – between 0.33 and 0.8ppm but aim to achieve a minimum level of 0.33ppm where possible

Guidance Note 2: Where designated sentinel outlets are fitted with TMV/TMT, the temperature of the hot and cold supply must be measured by surface (contact) temperature measurement. If contact probe is to be used for temperature monitoring through copper pipework, Temperatures must be collected as described in BSRIA Application Guide AG 4/94 – Guide to Legionellosis – Temperature measurements for hot and cold water services. The temperature measurements shall be carried out at different times during the day in order to allow indicative temperature monitoring of the system during a typical daily usage profile.
